Answer:
Strong positive
Explanation:
In studies, we usually establish relationships between two or more variables using correlations. Correlations tell us how this variables are related.
- Two variables have a positive correlation when if one increases the other increases too.
- Two variables have a negative correlation when if one increases the other decreases and vice versa.
Also, a correlation can be weak, moderate or strong. Researchers agree that a correlation that is larger than 0.70 should be considered a strong correlation.
In this example Isabella reads about a study saying there's a correlation coefficient of +0.85 between hours spent studying and final exam grade. <u>The fact that the sign of this correlation is "+" tells us that it is positive</u> (the more hours spent studying, the better final exam grade). We can also see that <u>the coefficient is 0.85 which is greater than 0.70 and therefore we can consider this correlation as a strong one.</u>
Thus, Isabella would conclude that this is a strong positive relationship.

Explanation:
Answer:
Length = 19 Cm
Explanation:
Given:
Perimeter of a rectangle = 68 Cm
Assume:
Width (B) = a
Length (L) = a + 4
Find:
Length of rectangle = ?
Computation:
Perimeter of a rectangle = 2(L+B)
⇒ 68 = 2(a + a + 4)
⇒ 68 = 2(2a + 4)
⇒ 68 = 4a + 8
⇒ 68 - 8 = 4a
⇒ 60 = 4a
⇒ a = 15 Cm
So, Width (B) = 15 Cm
⇒ Length = Width (B) + 4
⇒ Length = 15 + 4
Length = 19 Cm
